In its centuries-long efforts to dismantle the load-bearing structures of traditional and classical liberal society, Marxist dogma in its various forms – communism, socialism, neo-Marxism, Cultural Marxism – has embarked on a sustained campaign to weaken and ultimately to abolish the institution of marriage as it has been commonly understood since time immemorial. The dissolution or misprision of marriage, as a contract between a man and a woman committed to raising a family and recognizing its attendant responsibilities, is a prerequisite for the revolutionary socialist state in which the pivotal loyalty of the individual belongs to the sovereign collective, not to the family.
Advocacy and legislation that sunder the intimate love between a man and a woman, that deprive children of male and female parental role models, that compromise the integrity of the family and that dissolve the purpose of marriage as a guarantor of cultural longevity are indispensable strategies essential to realizing the left’s master plan. Dismissing the nuclear family as an archaic and repressive arrangement whose time has passed, the state would then operate in loco parentis.
The problem for the left is that the family is a traditional dynamic that precedes and eclipses the tenure of the authoritarian state, not only because it encourages a prior allegiance, but because it allows for the retention of inheritance and property rights within the generational unit. This is anathema to the Marxist vision of, in historian Jacob Talmon’s phrase from The Origins of Totalitarian Democracy, the “all-property-owning state,” a function of “political Messianism.” The Marxist offensive against marriage may be seen, in part, as the ideological version of a corporate takeover.
